I design industrial-grade power electronics and embedded control systems that work reliably in real-world, high-power environments With +13 years of hands-on experience in motor drives, inverters, SMPS, and embedded controllers, I help companies and startups turn complex electrical concepts into tested, field-proven hardware. -------------------------------------------------------------------------------- My work spans end-to-end development: # Power stage design (IGBT / MOSFET, high-voltage & high-current) # Embedded firmware (STM32, ARM Cortex-M) # PCB design (Altium Designer) # Control algorithms, protection, and real-world validation ---------------------------------------------------------------------------------- I have designed and tested systems such as: # 7.5 kW & 3–5 kW three-phase motor drives # 3 kW battery-to-220 V UPS/inverter # 300 kVA digital alternator voltage regulator (field excitation) # High-voltage inverter prototype up to 8 kV # MPPT solar charge controller (real PV-connected testing) # Industrial SMPS and flyback power supplies # SMS/GSM-based industrial relay controllers Unlike purely academic designs, my projects are built, powered, stressed, and validated on real equipment, including industrial generators, motors, and solar panels.
